I will pass this on to our tech guys, who can probably answer most of itbetter than I can. Two things that I can comment on: the crops grown in thevery center of B5 will be grown under artificial lighting conditions toreplicate natural light. Heck, we've already got lights that can be usedunderground and in nurseries for that purpose...and creating such anenvironment that way is easier than a complex system of mirrors and windows(and windows are at best problematic, now matter how strong they are).

Second it *does* take quite a bit of time to fully decelerate fordocking. One option you have to save time is the energy-dampers positionedquite a ways outside B5. We're still working out the technology on that one,but it *seems* to hold up.

Oh...and yes, we're looking at a gravity range from 0 to 2Gs. Anybodynot content with that can bloody well deal with it.
